Heineman and published by . This book was released on 1987 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preparation, characterization and application of electrodes with specific chemical properties that are imparted by surface modification with polymer networks are the long-range goals of this research. Networks that are formed by crosslinking with gamma radiation have been evaluated with respect to swelling in aqueous solution, retention of polymer in the network, permeability, and the effect of radiation dosage on all of these properties through its control of crosslinking. Ionic water-soluble polymers such as polyDIALLYL DIMETHYL AMMONIUM CHOLRIDE, poly VINYLBENZYL TRIMETHYL AMMONIUM CHLORIDE, ploySTYRENE SULFONIC ACID, SODIUM SALT and polyACRYLIC ACID, which would ordinarily dissolve from the electrode surface in aqueous solution unless crosslinked into a network, and several neutral polymers such as polyACRLYONITRILE, polyETHYLENEIMINE, polyDIMETHYLSILOXANE and poly VINYL ALCOHOL have been investigated. The covalent attachment of organic and inorganic redox mediators and enzymes to networks by gamma irradiation of a mixture of polymer and the agent have been investigated. Network-coated electrodes with the appropriate properties are being developed for specific applications that required a stable, easily fabricated, fouling-resistant, rapidly responding, sensitive, and selective electrode.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrogels are a fascinating class of polymers which show an immense ability of swelling under the influence of temperature, pH value or concentrations of different species in aqueous solutions. The volume change can amount up to several hundred percent. This unique behaviour is already used in such applications like disposable diapers, contact lenses or drug-delivery systems. The ability to perform mechanical work has been shifted the technical interest more and more towards sensors and actuators exploiting the thermo-chemo-mechano-electrical coupling within hydrogels. The accuracy requirements for such devices are much more demanding than for previous applications. Therefore, a deep knowledge of both the material and the functional properties of hydrogel sensors and actuators is needed. The monograph describes state of the art and recent developments for these materials in sensor and actuator technology.
